This Information Paper presents the Australian Bureau of Statistics methodology for estimating the prevalence of homelessness from the Census of Population and Housing. This methodology was developed in consultation with the ABS' Homelessness Statistics Reference Group and builds on the review that the ABS conducted on the development of official estimates of homelessness. The ABS' statistical definition of homelessness underpins this methodology. More information on the definition can be found in Information Paper: A Statistical Definition of Homelessness (cat. no. 2922.0)
